I realize that....
Let's- set the record straight here.
Do you think the current implementation of federation works well?
I believe the current implementation wont scale because instances won't be able to handle every subscribed federated action. Having a hub server doesn't reduce the number of subscribed federated actions, only whom they come from.
But- if we take that action of handling the federations, and seperate it from the main application server(Allowing the main instance server to focus on handling its local user-base), and architect it in a way that allows scaling the number of proxy servers up and down-
Would that not sound like a big improvement to scalability?
The node still needs to receive every subscribed federated action and insert it into the local database. This has to be local to the "main application server". Your proxy servers don't reduce the number of federated actions. It only reduces the number of servers needed to communicate with.
I feel that the bottleneck will be the total number of federated actions, not which servers deliver them.
